FRANK J. FRIES, F PACIFIC, MISSOURI.

PLOW.

Application filed April 30, 1917.

To all whom it may concern:

Be it known thatl FRANK J. FRIEs, a citizen of the United States, residing at Pacific, in the county of Franklin, State of Missouri, have invented a new and useful Plow; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to plows.

One of the objects of the invention is the provision of means for quickly disengaging the plow-share from the moldboard.

A further object is to provide an improved means for securing the share to the moldboard and to its attendant landside.

Other objects will appear in the detailed description which follows.

It is to be understood, that applicant is not to be confined to the exact construction herein disclosed, but that changes may be made, within the scope of what is claimed as practice may suggest.

Figure 1 is an elevation of the plow looking at the land sides.

Fig. 2 is a plan view looking up from the bottom.

Fig. 3 is an elevation looking at the rear of the mold board of the plow.

Fig. 4 is a section on the line 411 of Fig. 3.

Fig. 5 is a longitudinal sectional view through the locking and releasing lever and its attendant J-bar.

Fig. 6 is a plan view of the locking lever and the nut pivotally mounted thereon.

Fig. 7 is a section on the line 7--7 of Fig. 6.

Referring to the drawings, 1 designates a horizontally disposed landside to which the moldboard 2 is secured at the proper angle with relation to the landside. At the forward end the moldboard is secured to the landside by the U-shaped member 3, one of whose legs 1 is attached to the moldboard by rivets 5 and whose other leg 6 is secured to the landside by the rivets 7. Near its rear the moldboard is further secured to the landside by a bar 8. One arm 9 of this member is attached to the landside 1 by rivets 10 while the arm 11 is attached to the moldboard by rivets 12. The transverse piece 13, connecting the arms 9 and 11 together, is disposed at such an angle as to provide a suitable abutment surface for the lever 14 to engage Specification of Letters Patent.

in performing its locking function yet to be described.

The arm 11 of the bar 8 extends below the lower edge of the moldboard 2 to provide an abutment against which the share 15 may lie when attached to the moldboard. At the rear there is secured to the share 15 by rivets 16 the lug 17 which extends far enough above the upper edge of the share to permit it to lie against the moldboard on the back and to act as a means for further securing the share in place.

At the forward end, the landside 1 is provided with a nose 18 of substantially half the thickness of the landside. In this nose a longitudinal slot is formed which slot receives a rib 19 rigidly connected to the share landside 20 which forms a part of the landside, the latter being narrowed Where it connects with the landside 1 and the rib 19 being secured on this narrowed portion.

On the back of the share 15, there is secured by rivets 22 a lug 21 whose free end is slightly offset and provided with a suitable hole which the hooked end of the bolt 23 engages.

The shank of the bolt 23 passes through a hole formed in the transverse piece 13 of bar 8. The shank of the bolt 23 is threaded where it projects through the transverse piece 13 and receives on this threaded end a nut 24 with diametrically disposed trunnions 25 by means of which the lever 14 is secured to the nut. The lever 14 has a bifurcated end whose legs 26 straddle the nut and have holes formed in them wherein the trunnions 25 effect a pivotal engagement. In outline, the greater portion of the legs 26 are elliptical and the pivotal mounting of the nut 24 is eccentric to this outline.

In Fig. 6 the nut is shown as having trunnions 25 but it is obvious that these may be replaced by pins inserted on the edge of the nut at diametrically opposite points, as shown in Fig. 5 and designated as 27 therein.

It will be observed that the share 15 may be easily connected to or disconnected from the moldboard 2 and its attendant landside 1. Turning the lever 1 1 over so as to bring the flat edges of the legs 26 against the transverse piece 13 will obviously operate to release the pull on the bar 23, when the latter may be further loosened by turning the nut 24 around the threaded shank of the bolt 23 until the bar can be moved sufficiently to permit its disengagement from the plate 21. The share 15 can then be easily disengaged for repair or for replacing.

In connecting the share to the moldboard and to the landside, the rib 19 is positioned at a point ready to enter the slot at the end of the landside 1. The share is then raised to bring its upper edge into contact with the lower edge of the moldboard, when the plate 17 engages the moldboard on the back and the share reclines against the lower end of the lug 11. The rib 19 having effected engagement with its attendant slot by the time the edges of the share and the moldboard are brought together. The share is then secured to the moldboard and landside by hooking the bar 23 into the plate 21 and operating the lever 14 to create a pull on the bar and thus sustain the share in place.

What is claimed is;

The combination with a moldboard and land side of a plow having a detachable plow share, of means for holding said plow share on the land side and moldboard, said means comprising an apertured lug carried by the share, a bracket formed from a single piece of strap iron having one of its ends secured to the inner face of the land side and its other end secured to the inner face of the moldboard, said bracket having a central arch portion, which portion is bent so as to form a transversely disposed portion substantially at a 45 degree angle, in which an aperture is provided, a locking bolt having its threaded end disposed in said aperture and its other end provided with a hook adapted to engage an apertured lug carried by the plow share, and a cam lever adjustably threaded on the locking bolts and engaging the rear face of the transversely disposed angled portion of the bracket forming means for causing the locking bolt to move rearwardly and be held against forward movement, thereby holding the share in engagement with the landside and mold board of the plow.

In testimony whereof I have signed my name to this specification.

FRANK J. FRIES.
